TANK-BASE CAE'IING.

Specification of Letters Patent. p te t dq 25 1 2 )Appliea'tibn flledDecemher 9,4919. "Serial Now8485603.

Toatbl tu vo'm 5t may comm Be it known that I, JOHN HowannlMas TERS a citizen of the United States, and residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Tank-Base (Jastings, of which the following specification is a full disclosure.

This invention relates to a base casting adapted to have mounted upon its upper annular portion a tank or reservoir, and upon its upper rectangular portion, a pump-base casting or any similar casting, for the sup port of a suitable pump mechanism for 01) erative connection with the said tank.

It has been the practice to cast these buses in a single piece and in so doing a large amount of time has been consumed and material wasted. An advantage in casting the parts of this base separately and providing means for locking the said parts together to form a complete base is to very materially reduce the cost of the manufacture. Specifically. an actual reduction in foundry cost is thirty-three and one-third per cent, with a fifty per cent. increase of production by the molder. An additional advantage is the application of lugs to the upper side of the annular portion of my casting for se curel seating a tank.

Ot er advantages will appear in the specification and drawings and will be specifically referred to in the claims.

Figure 1 is a top plan view of my complete base-casting.

Fig. 2 is a reverse plan of the same.

' Fig. 3 is an enlar ed fragmentary reverse plan of the central Tockin means.

Fi 4 is an enlarged en view of the male mem er.

Fig. 5 is an enlarged end view of the female member.

Fig. 6 is an enlarged fragmentary reverse plan of one of the base locks.

Fig. 7 is an enlarged end view of the female member of the same.

b Fig. 8 is a similar view of the male mem- The base for a combined tank and pump comprises three castings respectively interlocked together, there bein a rectangular casting 1, having the rim ange 2, on its under side, portions of the rim on one of the sides being cut out to form the locking recesses 3, for the segments of the annular casting. This annular casting for supporting the tank is madein two separate segments d, 5, respectively, counterparts ojfone smother. The ends of these-Be ments aidi'acent the casting l are forme with the ock lugs 6, 7, adapted to interlock into the recesses 3, 3', of the rim of casting 1. These segments are formed with outer and inner rims 8, 9, on the under side, and with the bracing cross ribs 10, ll, 12. The interlock for the abutting ends of these segments t, 5. consists of a-lock lug 13 cast on the under side of the member 5 between the rims and having a latch projection 14, fitting into the recess 15 of the inner rim of the abutting segment 4, the major portion of this block projecting endwise beyond the end of member 5 and into the space between the rims of the abutting member 4. On the upper face of these segments are cast three lugs 16 for securely seating the tank on the annulus formed by the interlocked segments. These segments are securely interlocked in relation to one another and to the member 1, forming a strong, unitary base for a combined tank and pump.

Having described my invention, I claim:

1. A base for supportin a combined pump and tank, consisting o a rectangular casting, and two segments of an annulus, all of said castings being formed with flange rims on their under sides, the abutting portions of the segments and rectangular castings being formed with interlocking lugs and recesses, and the abutting ends of the two se ments being formed with a lug and recess interlock, the recesses being formed in portions of the rims of the respective castings.

'2. A base for supporting a combined pump and tank, comprisin a rectangular castin and two segments 0 an annulus, all forme with flange rims on their under sides, the abutting portions of the se ment and rectangular castings bein forms with :1 lug and recess interlock t rough a rim portion, one of the abutting ends of one of the se ents being formed with a In between lts flange rims projecting beyon the end of that segment and having a latch end, a rim portion of the abutting end of the adjacent segment having a locki recess, said lu projecting between the rim portions 0 said adjacent segment.

3. A base for supporting a combined pump and tank consisting oi n summrtiu g misting for the pump and two oust members together constituting a support for the tank, all of Silitl castings being formed with flange. rims on their uinler sides, the abutting portions of said two cast members for the tank and the eastin r for the pump being formed with interlocking lugs and re cesses, and the abutting ends of the said two cast members being formed with an interlocking; lug and recess.

4. A base for supporting a combined pump and tank consisting of a supporting casting for the pump and two cast members of u tank supporting part, the abutting portions of the said two cast members and the tank supporting casting being formed with interlocking lugs and recesses, and the ubuL- ting ends of the said two cast members being formed with an interlocking lug and recess.

In witness whereof, I hereunto subscribe my name, as attested by the two subscribing Witnesses.
